Security alarm: 1) wireless access mode: four infrared defense zones (the third and fourth defense zones are shielded during home defense, and the number is101,1 100), as well as gas detection and alarm. The above defense deployment and defense release control can be realized by wireless remote control, terminal Chinese menu operation and remote control. 2) Wired access mode: alarm display of seven self-defined defense zones, defense deployment and defense deregulation of the above seven defense zones; 1 patrol protection zone, gas detection alarm port, smoke detection alarm port, door magnetic protection zone alarm port, manual secret button alarm port, * * * 12 protection zone. Home appliance control: Four control ports can be closed and opened manually in the management center. These control ports can manage water, electricity, gas meters and any household appliances, and the control ports can also be connected with any household appliance control ports to control the switch of household appliances. 2.3 Intelligent lighting system * Rich control methods: @ Touch weak current switch: local lighting can be directly controlled according to usual habits; According to your needs, the switch can set the required control objects at will, for example, the button in the hall can be used to turn off all the lights; In this way, when you go out, you can turn off all the lights with a little light, which is energy-saving, safe and very convenient. @ Infrared Remote Controller: In any room with a key panel, use an infrared handheld remote controller to control the on-off state and dimming state of all networking lights (whether the lights are in the room or not); You don't need to turn on the light after entering the room. You can turn on the light with the remote control before entering any room, and you don't have to look for the light switch in the dark anymore. @ Telephone Remote Control: Remote control of lights or scenes can be realized by any ordinary telephone or mobile phone. This function can be used to simulate the lighting situation in the owner's home before going home late to confuse possible thieves; @ Computer/Internet Control: You can remotely control the lighting status through a local computer or a computer on the Internet; @ Time Scene Control: Through the time scene controller, you can define the timing on and off of the lights. For example, at 7 o'clock every morning, slowly turn on the light in the bedroom to the appropriate brightness; In the middle of the night, turn off all the lights automatically. * Flexible scene switching: @ You can define up to 32 different scenes, and you can control the working state of any lighting, brightness and even other electrical equipment according to your own needs (such as turning on the TV and switching channels); * Good dimming effect: @ Microprocessor is adopted to accurately control the change of illumination through the program; @ You can set the speed of brightness gradient, which can be adjusted at will from 1 sec to 3 minutes, providing more abundant effects of on-site lighting transformation; @ Using advanced zero-crossing trigger voltage regulation technology, the interference of dimming circuit to power grid is greatly reduced; * Close integration with other systems: @ You can easily associate your lighting system with other devices and respond to signals sent by other nodes; For example, if you turn on the TV in the living room, the lights in the living room will automatically dim and all the other lights will be turned off. @ Lights can be set to automatically adjust for a light sensor; The lighting system can adjust its state according to the brightness-when the sky gets dark, the lights in the room automatically turn on, and so on; Can be connected with a human body detection sensor, and the light will automatically turn on when you pass by; 2.4 home appliance control system 1. Infrared remote control of household appliances: The system can learn the control keys of infrared remote controllers of almost all types of household appliances, and can simulate the keys of infrared remote controllers to control equipment, so that users can concentrate the functions of infrared remote controllers of multiple household appliances into this system and control them through one remote controller, which will help you get rid of the trouble of constantly changing remote controllers and facilitate your life. Even if you are not in the same room, you can still remotely control the working state of an electrical appliance. For example, in order to prevent children from indulging in TV excessively, you can control the switch of TV at any time. 2. Start-stop control of household appliances: There are many appliances at home that need to change according to time and environment. For example, when the host is at home, the background music system should be turned on, but it should be turned off during entertainment time or late at night; Central air conditioning can only be started at home or by remote control; When the window is open, it is not recommended to turn on the air conditioner ... These details are basically managed by the owner himself, but in the automation system, it will be adjusted in time by a logical system. This not only brings more convenience, but also saves energy consumption for people. For example, many families are equipped with drinking fountains that use pure water and have automatic heating function. After leaving home, the water dispenser doesn't need to be heated often. Take an ordinary 500W drinking machine as an example. It may go out without heating for 8 hours every day. Assuming that the water temperature drops naturally for 2 hours, at least 1 kWh of electricity is wasted every day. In addition to energy consumption, frequent cooling and heating of drinking water will reduce the water quality. It can be seen that it is necessary to increase automatic power control for household equipment similar to drinking fountains. 3. Cooperation among various devices: Controlling household appliances through ESIR can provide more system-related functions. For example, when you are ready to watch TV, the lighting in the living room is automatically adjusted to your favorite brightness (realized by the dimming control module), the curtains are automatically closed (realized by the curtain control module), and the TV is turned on and adjusted to your favorite channel ... For example, when a phone call comes in, the sound of the TV is automatically lowered by the system. When there are guests at home, the lights will automatically turn on, adding a happy atmosphere, and the stereo will automatically play cheerful music and so on. An important step in the networking of household appliances is to provide remote access capability for household appliances. The following remote management methods of household appliances can be provided: l Internet: remote access through WWW browser of any Internet device in the world; L telephone: use any ordinary telephone or mobile phone for remote access and control; During remote monitoring, you can control all the devices connected to the home network, such as the brightness and switch of each lamp in the lighting system, the start and stop and temperature of the air conditioner, the start and stop of the ventilation equipment, and even the channel and volume of the TV. During telephone control, 32 preset scenarios can be selected, and remote operation of multiple devices can be easily completed. 2.5 The security subsystem is equipped with some sensors at proper positions in the house, including double detectors, mobile detectors, glass breakage detectors, sound detectors, door magnetic switches, etc. It can be set to perform a series of actions when these sensors are in a certain state. For example, when there is illegal intrusion in the home, the smart phone controller sends out a remote alarm, and the light dimming unit turns on the light ... Compared with traditional security products, it has the following characteristics: 1. The security system is closely integrated with the whole home network, and the action or state of any equipment in the home network can be triggered by the sensor in the security system; 2. Various safety modes can be designed by computer, providing very flexible trigger and drive modes to meet the needs of different situations; 3. The alarm information can be called to the user's mobile phone for voice prompt as needed; For example, there are the following sensors: the number of module positions triggers the door magnetic switch porch 1 normally closed, the glass breakage detector living room 1 is always closed when triggered, the harmful gas detector kitchen 1 is always closed when triggered, and the smoke detector living room 1 is always closed when triggered. The living room 1 of intelligent curtain infrared detector is normally closed when triggered, the emergency call button of the main bedroom 1 is normally open when triggered, and the main bedroom 1 is normally open when triggered. If the time control module is matched, the following security modes can be designed: if (current hour >: 2 1) and (main security mode = 1), turn on the living room TV; Tune to 1 channel; Turn on the light in the living room; Turn on the bedroom light; If (current hour = 00) and (main safety mode = 1), turn off all electrical equipment; Turn off all the lights; Turn on the wall lamp in the living room; This design can complete the following functions: if the owner has gone out and has been protected, then if he hasn't come home by 2 1 at night, he will start to simulate the state of the owner at home to confuse the thief. At midnight (0: 00), the system will also simulate the state that the owner is asleep, and the security system is still on all lines. 2.6 Overview Home Intelligent System provides users with the functions of unified management of household appliances, lighting control, power control, indoor wireless remote control, burglar alarm, home security, temperature and illumination detection and adjustment, telephone remote control, Internet remote control and so on. It will bring more security, comfort and convenience to your home life! The development of smart home improvement is the last word.
